Hi,
I always used Tuya. but now I’m starting the migration to Z2M. In my new house I have 6 zigbee touch switches, and with Tuya I can’t use them in a group, the maximum is 4.
I can’t test my Z2M on my new house for now, so I’m testing now with 3 equal zigbee power sockets, and my idea was that in a group the on/off switch option works for all.
But now here I’m not getting the desired behaviour. If i use the group “State” button in fact all respond, not at the same time… few ms delay, but what I was expecting was that if u press the physical button all of them will switch on/off, and this is not happening 
I tried to use the binding function… but no luck at all, seems very confusing with the “clusters”… so no clue to make this work as desired.
I made other test to use my know switch to power on/off my power sockets, but even I added it to the group, I’m unable to control them.
Any help here guys? Or even oher possible idea to make this better than tuya?
Thanks and Best Regards
